This is especially true if you are just using a solar battery as backup power storage.

However, in some cases, other battery types, like lead acid batteries, could work better for you. Plus, their higher efficiency means that you get to use more of the energy your solar panels produce and store - giving you more bang for your buck. The battery will last longer, so it won’t need to be replaced as often as a lead acid battery. Also, their high DoD means you can use more energy stored. Lithium ion solar batteries are the best solar energy storage system for everyday residential use because they take up little space while still storing a substantial amount of energy. When is a lithium ion solar battery the best choice? However, this risk of a properly installed lithium ion solar battery is slim to none. Lithium ion batteries run a higher risk of thermal runaway, which means they catch on fire. Plus, although lead acid batteries may be cheaper - they have to be replaced more often than long lasting lithium ion systems. The good news is that solar battery systems qualify for incentives like the federal tax credit, which helps make lithium ion batteries more affordable. Lithium ion batteries tend to be the most expensive battery storage option, especially when compared to lead acid batteries. The disadvantages of lithium ion solar batteries include: Lithium ion solar batteries do not require maintenance like flooded lead acid batteries do. Not having to worry about regular maintenance is one of those advantages that you just can’t put a price on. Lithium ion batteries have efficiencies between 90 and 95%. Lithium ion batteries have a higher round-trip efficiency rating than other types of solar batteries on the market.Įfficiency refers to the amount of usable energy you get out of your battery compared to how much energy it took to store it. Lithium ion batteries can store more power without taking up as much space as a lead acid battery, which is great for homes where space is limited. The energy density of a battery is how much power the battery can hold relative to the physical size of the battery. Lead acid batteries, on the other hand, only have warrantied lifespans of around 5 years. Most lithium ion solar batteries have a minimum warrantied lifespan of around 10 years, or a cycle life of 10,000 cycles - whichever comes first. Long lifespanīecause lithium ion batteries have a high DoD and don’t need to be charged and recharged as often, they have a long lifespan. This means you can use more of the energy that’s stored in a lithium ion battery without having to charge it as often. Many lead acid batteries only have a DoD of 50%. Lithium ion solar batteries are deep cycle batteries, so they have DoDs around 95%. Most batteries come with a recommended DoD in order to maintain the health of the battery. The DoD of a battery is the amount of the stored energy in the battery that has been used, as compared to the total capacity of the battery. The advantages of lithium ion solar batteries include: However, there are some cases in which a lead acid battery might be a battery choice to store your solar power. The reason why the introduction of lithium ion solar batteries rocked the solar industry is because the technology offers a variety of benefits over lead acid batteries.

What are the pros and cons of lithium ion solar batteries? Solar expert Will White explains how lithium ion batteries work in the below video: Are lithium ion solar batteries the best battery for solar panel systems? However, there are now many lithium ion solar batteries on the market, so every homeowner can find the right option for them.īut despite all the hype of this new technology, the industry and analysts alike have forgotten to ask one simple question. Prior to the development of the Tesla Powerwall, most solar storage systems were composed of lead acid battery banks. Powerwall paved the way for the future of lithium ion solar batteries - establishing pricing of battery energy storage, driving investment in the energy storage sector, and creating hope that battery technology could become affordable for average residential customers. It also propelled Tesla to be one of the top battery manufacturers in the U.S.

The launch of the Powerwall 1 ignited a torrent of discussion and research about energy storage and the development of cost-effective solar batteries. In 2015, popular EV manufacturer Tesla announced their new lithium ion solar battery, Powerwall 1, inspired by the technology used in their EVs. Lithium ion batteries are commonly used in rechargeable electronics like cellphones and in electric vehicles (EVs). Lithium solar batteries are a rechargeable energy storage solution that can be paired with a solar energy system to store excess solar power. Show more What is a lithium ion solar battery?
